Application filed. February This invention relates to new and useful improvements in woodworking machines, and particularly to machines for treating sash stiles for the reception of the sash cords.

The principal object Vof the invention is to provide a machine which automatically feeds sash stiles from a hopper or magazine, and which bores one or more sockets in the edge of the stile, and plows aV groove or grooves for the purpose of the reception of the sash oord. 1 i

Another object isl to 'provide a' machine of this character wherein the operations of boring and plowing are pei-formed automatically', as the stile is carried through the machine. i

Another object is'to providemeans whereby the carriery belt is vadapted to VtravelV continuously, whereby to permit actionofthe boring and plowing tools on the work, withoutinterference of the belt, means being also provided for holding the work while'the belt continues. Y

Another object is to provide a carrier i chain which is equipped with means for au-V tomatically moving theboring lmeans into operative position, and to subsequently move the plowing tools into cutting engagement with the stile. 1

Other objects and advantages will be apparent from the following description when taken in connection I with the accompanying drawings.

able source,vnot shown. 4Engaged around the -belt wheels 23 and 24 is a l,drive belt 31,

while a' drive belt 32 is engaged'around the wheels and 28. A drive belt l33 is engaged around vthe beltV wheels 2O and 2 9. Onthe end of the vertical portion `1O-,are mounted the :bearing brackets 34which support they shaft 35, earryingthe wheel 36.

Bothof the wheels 21 and 36 'are peripher- Y ally grooved and-have the bottom" walls of said' grooves lV-shaped in conforimlty with the groove 11, of the frame. 1t will be noted that the shafts 19V and 26 extend transversely through' the vertical portion of the `frame'.

Y YMounted on one side of the fvertical por ltion of the frame are the vertically alined pairs of brackets37 and V38, respectively,

supporting the vertical shafts 39 and 4Q.l

Fixed on the fuppe'r ends of these shafts are the plowingtools onsaws 41 and 42. respectively, the former being of greater thickness than the latteigbecauseof the fact that 'the said former saw is adapted `tocut a groove of greater width than the latter saw.v 0n

thevshaftl() are fixed theble'ltfwheelsj 43 andl v44, the former of which isi driven. by the belt 45, from thefbelt Vwheel23.y OnY the' other shaft 39 there is Xeda Vbelt wheel'f46,;which yisdriven from the belt-Wheel 4,4 bythe belt.

V 50 is received vertically '47, whereby both of the respectively, are the threadedl shafts andV 5l.Y The intermediate portion or the shaft throughthe intermediate portionv oiE an'arm 52, and a tasteningvpin 53 engaged through the arm and shalt whereby to secure the parte together. One end ot' the arm 52 is termed withv a yoke 54 vertically through the arms ol" which is loosely disposed the upper portion ot the Shaft 40, while the other end ot the arm has longitudinally extending` 'and longitudinally adjustable extension 55. Carried by the outer endet the extension 55 is a transversely adjustable `member 56, and rotatably sup-1 ported in the outer end ot' this member 56 is a roller 57 to which more particular mention will be made later herein. The shatt 50'is provided with adjusting nuts 5S on the upper and lower ends, above andbelowv the ears 48, whereby said shaft may ie adjusted vertically, to raise and lower the arm 52, whereby to position the saw 42 properly with respect to the work. rlhe shatt 5l is disposed'vertically through the intermediate portionot an arm 59, and has'adjusting nuts on' the upper and lower ends, above and below the ears 49. One end ot the arm 59 is formed with a yoke 60', the arms otwhich loosely and vertically receivey theV shatt 39 therethrough. The other end of the arm carries the adjustable extension 6l, on which is adjustably mounted the member 62, which has the roller 63 in its :tree end.v The arm 59 is adapted to swing on the shatt 5l to move the shaft 39, and its saw41l toward and away fromthe work. l

Engaged around the grooved wheels 2l and 36 is the work carrying chain,p `desig natcd` as a whole bythe numeral 64. This chain is made up ot a plurality ot links 65, properly pivote'd together, and veach having a longitudinally extending V-shaped rib V66, on its lower or inner tace 'for engagement in the`v groove ll et the trame. The widthot the chain is'4 approximately'the same as the width of the wheels 2l and 36, whereby the Jortions of the links at opposite sides of the rib, ride on the peripheries ot the lan'ges of said wheels, y,while the .ribris disposed therebetween. Mounted on the table','or upper tace ofthe vertical portion 10, is a longitudinally extending'J and transversely adjustable work guiding tence 67 said 'tence ybeing disposed in close proximity to one edge of the carrier chain. Secured to corresponding sides of a consecutive series ot links of thechain, are the outwardly es- Y tending plates 68, the e-ndmost of which have `their outer end portions cut ott obliquely, :is shown at 69, for proper engagement with shafts 39 and 40 will Y diterent widths.

Leonel? tending horizontally outward trom rearinost oii'the links whiolrcarry the plates 68, is a stub shaft 72, and rotatably supported on this shaft is a roller or wheel 7 3, while on theV upper Jace ot one ot the links, a short distance rearwardly of the wheel 73, is a vertically extending lug 74. Mounted on theltrame below the extension l2, is a transverse rock shaft 7 5, Vone end ot which is provided with a vertical opera-ting lever 7 6,

while the other end is provided with a radial weighted Varm? 7 carrying ya roller 7 8 on its theA armsis a spring Vouterv end' ior engagement with the upper lap et the drive belt 33, for the purpose ot' stopping and starting the carrier chain.

Supported on the trame, in proper spaced relation above the carrier chain, are the vertical channel members 79and 80, which torni the magazine and receive'the stiles to lbe treated. These members 79 and 8O are adjustable on the trame to accommodate stiles ot different lengths, as each of the members includes an adjustable portion S2, which is movable with relation to the other part,'to accommodate stilcs ci" lt will be noted that the lower ends ot the members 79 and 8O are disposed a certain distance above the face ot the carrier chain, 'such distance being approximately that ot the thickness oit a stile to be treated. and whereby a single stile may rest on the chain and he readily moved'iirom beneath the pile ot stiles, by the lug 74V ot the carrier chain'. 'v

Supported 'For verticalV adjustment on om` side ot the vertical portion of the trame ot the machine` is a bracket 63. and formedin theupper lace ot this bracket` transversely et the said trame. is a dove-tailed groove 84 shown at 81, while lOl: v

uev

in which is slidably disposed `the bevel-edged vable or bed plate 65.- Properly supported on this bed 85 are the parallel sbatte @Sacarry' intermeshing gears 87,'and in the end' ot eachV oie the shafts, adjacent the slle'o't the chain'64, is formed chuck 89h for the reception'ot a bit 89, said shafts and bits be ing arranged obliquely with relation to' the chain, whereby to'bore sockets in the side tace of a stile atV an angle with respect to the stile.V Supportcdon the trame. adjacent the carrier chain; and opposite the magg# azine, is an upright 90.' Fivotally su ported in the upper end ot this uprightris one portion ot an angle lever 9i, the 'lowerrendr yot the vertical arm of which-is disposed in the path oittravel olf the'roller 7 il, whereby to causethe leverftobe rocked, as the carrier chine. Mounted on k,the side of the frame is a grooved roller 92, and secured at one end to the. free ory outer end of the horizontal arm of the lever 91, is aflexible element 93, which may be a cord, wire, chain,lor the like, the other end vof ysaid elementV passing through an opening 94, in the frame, and being lSecured to an Vadjustable eye-bolt 95, carried by the bed 85. rlhus, astlie roller 73 engages kthe lower end ofthe vertical arm of the lever 91, said arm will be rocked on its pivot with theresult tliat'the flexible element will draw the bed toward the chain to engage the bits with the edge face of the stile. Also carried by the forward end of tliebed 85 is a `pair of arms 96, each of which carries a forwardly projecting pin 9T `for engagement in the edge face of the stile, whereby to hold the stile against movement` as the chain continues to travel foi'- wardly, said chain easily sliding beneath the stile. lThis operation takes place whilel the stile is at rthe Vbottom o'f the magazine, and

at the proper interval preceding the engagementof the lug, Tiwith the end of the stile. forward speed vof the carrier chain is commensurate with the speed of the bits, whereby when the roller 73 lias'snapped past the arm of the lever 9,1, the bits have completed Vtheir boring operation in the edge face of the stile. -The arms 96 are resiliently supported whereby t@ yield, to ya Vcertain extent, as the hed 85 moves forwardly toward the stile. Slidable through the frame of the machine, and adjustable.through an apertured lug 98, on the bed 85, is the before mentioned bolt or rod a coil spring being disposedonthe rod, and bearing against the said lug98, and the side faceof 'the frame, said spring being compressed as the bed moves inwardly, and serves to push the bed outwardly, at the completion of'the bor-.

ing operation, and when the roller 73 has passed the arm of the lever 91, as clearly seen in Figure 7.

On the outer end of one of the bit shafts 86`there is secured a belt wheel 1,00, which is driven by the belt 101, from the belt wheel 24, and whereby the bits are kept in constant rotation, ready for action on the stile when advanced thereto.

Upon the completion of th-e boring oper` ation on the stile, the lug 74 engages the rear end of the lowermost stile, or that stile which has been bored, and carries Vsame along on the vface of the chain.Y Then the advanced end of the cam plates strikesV the e roller 57 this roller is ushed awa from the side of the frame, with the' result that the arin52 is rocked andthe saw 42 pressed.

into cutting engagement with the edgeof the stile. The chain, being in constant motion, carries the stile along, whereby the saw land the frame, swings cuts a channel or groovein the edge face .of the stile1 l/Vhen the rearmostY-of the plates 08 has passed the roller 57, the saw'`V ,5e and the vside of the frame. As the chainv 6e moves onward the foremost of the yplates 08 engages with the roller 63 and rocks the saw 41 into engagement with theedge face of the stile, whereby to plow a groove ofV greater width in the stile face. When they rearniostaof the plates 68 has passedthe roller 68, a spring 102, between the yoke @Of Y the saw `away from the stile. The boring and plowing operations" having thus'been completedY onV the stile, said stile is removed or discharged from the chain, as said chain passes around the wheel21. Q

l fart approximately the instant that the s aw Ll2 has completed the plowing of the .narrow groove, another Yroller 73 has engaged the angle lever91, tov cause thejadvance of the..

bed 85,' and the boring of the next stile, which has dropped onto the chain 64, from the magazine. Thus, while one stile is beingV plowed, another. stile `is Abeing bored, with the result-that the operation is con-A tinuous, the stiles being'arranged in a line" on the chain, and being vsuccessively operated upon by the bits-and saws, to be discharged froin the far end of the chain.

Whe-ii it is vdesired Vto stop the' carrier chain, the operator grasps the-lever 76 an'd i'ockstlie rollered arm 77 upwardly, whereupon the belt `33 vvwill ibecome slack, and the chain 64 'ceases movement. Reverse movement of the lever 76 tightens the belty 33 and sets the chain 041 in motion. lllhatis claiinedris'z-V-V Y 1.
